these colors

Tomasz Wlostowski 2c6e9778a1 GAL: OpenGL draw calls pooling/splitting
Improves rendering performance, esp. for large designs by:
- using a separate glDrawArrays calls() for large buffers of contiguous vertices (e.g. large zone fills)
- pooling smaller items into a small-sized index buffer held in system RAM (has to be DMAed to the GPU by the driver anyway)

Mike Williams 30987cebfe Gerbview: fix cairo negative items and implement real differential mode

copying so they don't _CLEAR the draw items below them when a negative

Differential layers are basically the same thing only they use a

Jeff Young 27804e40e2 Go back to using space-width for tabs (instead of max-char-width).
The max-char-width impl was buggy and never applied to PCBNew anyway.
Plus the stroke font has a max-char-width of 2.8 time the space width,
so it made for really wide tab spacing.

Also fixes a bug where the Scintilla editors weren't getting a
monospace font on Mac.  (This bug may also exist on the other
platforms, but each would need its own fix.)

Also moves more of the Scintalla customizations to SCINTILLA_TRICKS
where they can be shared.

Seth Hillbrand ea283625a7 Further simplification of AA regime
Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good.  Fast AA

Good AA is super-sampled x2.

Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves.  Best is removed as it mostly affects text rendering
and not line drawing (as our text is)

Ian McInerney 11e6cac42b Introduce EGL backend support for the OpenGL canvas
wxWidgets 3.1.5+ on Linux will compile with the Wayland EGL
canvas as the backend instead of the X11 backend. This requires a
version of GLEW compiled with the proper EGL defines and a different
header/code for certain parts that are X11 GLEW specific.

This introduces an in-tree version of GLEW that will be built with the
GLEW_EGL flag then statically linked into the KiCad executables when
EGL support is needed.

Ian McInerney 5684708b22 Remove shadowing linewidth member from the Cairo GAL
The base GAL has the linewidth property already, and its
accessor will only return the base version. This was causing
problems with the Cairo printing GAL, since that setter wasn't
using the base class version. Also, this removes the print-specific
setter, since the actual setting of line width shouldn't be done
there and is instead done where the drawing happens.

mntmn bf60482b5c OpenGL GAL: support fallback without overlay buffer
On platforms with limited framebuffer attachments, like GC7000L
driven by the open source etnaviv driver, we can still use
GPU acceleration by drawing directly to the main buffer.

EDA_DRAW_PANEL_GAL::onPaint checks if an overlay target is
available in the GAL, and if not, redraws the whole view if the
overlay target should be dirty.

Clearing of the overlay target is a no-op if there is no overlay
buffer.

Move repeated GAL config reading routines into GAL_DISPLAY_OPTIONS.
THe app-level config is in here already, do the same for the

First, add automatic detection of toolkit DPI scaling options. For now, this
is, in order,

* Check the GDK_SCALE option under GTK+ (users can set this to force the scaling)
* Check the value from WX's GetContentScalingFactor(). This will start to work
  correctly from WX 3.1 and GTK+ 3.10.

Then, add a user-settable override in the main prefs panel, next to the icon
scaling. This is independent of the icon scaling options.

DPI handling is performed in a standalone class, so they can be shared between
the prefs UI and the OpenGL backend easily. Also means Cairo could use the same
interface in future.

Also adjust the OpenGL grid drawing code to use the computed scale factor,
which avoids over-thick grids in scaled environments (the user can manually
thicken the grid if wanted).

Tomasz Włostowski bbee30671a gal: pixel alignment hacks, works for Retina display too now.
gal: pixel alignment for Cairo.
gal: pixel alignment for OpenGL

Cleanup of pixel alignment patches

gal/opengl: more pixel alignment patches:
- works on Retina displays now
- pixel alignment for circles
- correct 1-pixel strokes
- fixed unfinished 1-pixel line ends

GAL: Restore antialiasing options in Cairo
GAL: Fix arc drawing

Removes DrawArcSegment, which drew arcs whose edge was optionally
stroked (a feature that we did not use).  Fixes Cairo arc drawing issue
where arcs were not visible in pcbnew.

gal: further cleanup
gal: removed unused shader parameter

Seth Hillbrand 7b3ef1b7ed colors: Add HSL conversion and tune colors
When adding colors to length tuner, we depend on the window background
color, which can be set by the user, resulting in an unreadable text.
This uses the HSL conversion to detect which shade it should use for the
coloring.

Also adds test cases for round-trip HSL and HSV conversion

Seth Hillbrand e8333633fe GAL: Add antialiasing options to Cairo
Cairo supports antialiasing when rendering but can be slow when set to
sub-pixel mode.  This bumps the minimum version of Cairo to 1.12
(available in 14.04 LTS as well as mingw) to support three antialias
settings (fast, good, best) that offer speed/appearance tradeoffs.

This can provide a higher-quality eeschema render as it works on a
per-element basis as opposed to the OpenGL per-screen antialias.
